One thought on “Zhenxuan’s Final Project Proposals”

  1. Great ideas, Zhenxuan! You can use the internet Valentine project code as a base for the first two ideas. For your second idea, to add sound, you could use your piezo buzzer or this sound fx board (easy to control with your Arduino): https://www.adafruit.com/product/2217 (and speakers: https://www.adafruit.com/product/1669). For your third idea, you could use a solenoid like this one: https://www.adafruit.com/product/1512 and here are similar projects: https://learn.adafruit.com/remote-controlled-door-lock-using-a-fingerprint-sensor-and-adafruit-io
